"Old Ben." After Qin saw a few employees, the old man immediately shouted from the back. This old man is the leader of Han's radar industry. The technology of airborne radar is under his leadership. The 114th Institute originally developed ground-based radars. Therefore, it is their strength to make this kind of ground-based mobile radar.

Now, Qin Guan looked at the old man's gray hair, and his heart was full of gratitude. He has contributed his entire life to the radar cause of the motherland.

"Mr. Qin, I am very happy to meet you." Ben Lao was also very happy to see Qin Guan. He came up to hold Qin Guan's hand and said, "This plan you proposed is less difficult than the other one. What a different plan, we don’t have a clue yet."

In addition to this meter wave radar, the other is passive radar, which uses radar waves that exist in the sky to detect. It requires several radars to work together to detect changes in electromagnetic waves in the area, and then you can find the target. This detection method is completely different from the principle of current radar. Therefore, after 114 has passed the demonstration, it is decided to make a breakthrough from this aspect first.

Qin nodded his opinion: "Yes, the other method is very difficult. Each has its own strengths. Now we concentrate all our efforts to develop this kind of radar first, which is also the best. This kind of radar is also very difficult. Right?"

No advanced technology can be achieved overnight. Qin Guan remembered that he did not provide much help in this regard, mainly because he wanted to watch the development and progress of domestic technology a little bit. Now, Qin Guan asked, Ben immediately Just started talking.

"Yes, the biggest difficulty is not the hardware, but the optimization algorithm specifically for the stealth machine." Ben Lao said: "With the same hardware, using the latest computer technology and performing a lot of calculations, you can accurately To find the location of the target, after all, we must not only find the stealth machine, but also have enough positioning capabilities to accurately find the target and provide guidance information for our missiles."

The biggest feature of the meter wave radar in the past was its poor accuracy and could not guide the missile to hit the target. The current phased array meter wave radar uses a large number of launch units to scan in the form of an array, and then combines the data obtained from each array Performing comprehensive calculations not only achieves the ability of three coordinates, but also allows this radar to have super high accuracy. When this radar comes out, all of them are very excited.

Of course, there are still shortcomings, such as its large size, but this is determined by the most basic principle of the meter wave radar, and this cannot be changed.

Meadow radar has been born in their hands, and now, I am looking forward to the first time that Meadow radar will be established!

In fact, when Qin Guan proposed this technical route, they had already begun to prepare. The earliest time was to install the meter wave radar on the domestically made Aegis warships, so that the Aegis warships had the ability to detect stealth machines. However, that The meter wave radar is still the most common, and the tactics used are different. It uses the meter wave radar to find the approximate position of the target, and then uses the phased array radar of the Aegis warship to concentrate all the beams, so as to achieve the lock on the stealth machine. And attack.

But now, it is completely using this meter wave antenna to both search and find and attack.

Next to the meter wave radar, there is also a launching position for air defense missiles. Here is the land version of the vertically launched ship-based air defense missile. It is the most famous Hongqi 9 air defense missile! When looking at the rectangular launch boxes, Qin Guan felt a kind of intimacy.

"In fact, the detection range of our radar is very long. We are confident that we can find a stealth machine at a distance of 500 kilometers. However, to accurately locate the stealth machine and have the ability to guide missiles, it must be shortened to one. Within a hundred kilometers, so, with this Hongqi 9 missile, it can exert the full power of the system, and an air defense circle of more than 50 kilometers can be constructed near our air defense zone."

Speaking of shooting range alone, it may reach a hundred kilometers, but shooting range and shooting height are two entangled concepts, and it is impossible to achieve all of them. Therefore, if you draw a circle with this place as the center, the one with a radius of 50 kilometers The spherical surface is the easiest to get.

Qin nodded his opinion: "What we want now is this breakthrough. Not only do we have a breakthrough in stealth machine technology, we must also have a breakthrough in anti-stealth machine. Moreover, after this experiment, we will soon It can be tested in actual combat."

In a few months, the Eagle Nation will send troops to invade a certain country. This country will also be threatened by a stealth aircraft for the first time. There, letting the Eagle Nation’s F117 fall into the sand will definitely bring them morale. One of the heaviest blows, right?

Qin Guan secretly thought in his heart that the world is not peaceful right now, and the best way to protect the sovereignty of the country is to continuously strengthen oneself, and to have the strongest strength is an eternal goal.

"Well, there are still a few hours before the interception experiment. Let's go to dinner first." General Lin said: "Although we are very nervous now, we must relax and face this experiment with a calm mind."

Everyone is very nervous, so nervous that they can't even care about eating. This state may be the best, but it cannot be maintained for a long time, so it is still necessary to relax and have a degree. Now, it is to eat.

Since it is in a field state, it is natural that there is no need to go to the canteen. The field cooking wagon is already ready. Even a small logistical support also reflects the progress of technology. People are iron and food is steel. If they don’t have food, the combat effectiveness of soldiers will decline.

The sky is slowly getting dark. The stealth machine’s attack must have been launched in the dark. Just look at the black coating of the stealth machine.

The setting sun sprinkled the last rays of light on the earth, and gradually fell into the mountains to the west. From a sunset glow, the earth gradually became vast, then darkened, and the night enveloped the entire earth.

It was a calm and ordinary night. On this night, in an unknown base, the door of the hangar was slowly pushed open, and a strangely shaped airplane was pulled out by a tractor. , The night belonging to the nighthawk, finally came, its black skin, dimmed under the light, its unique configuration of the body, in the light, is so sci-fi, leaving a piece on the ground Weird shadow.
